MapInfo MIF Format

Read MapInfo Interchange Format (MIF/MID) vector features via Fiona as GeoJSON-like Feature dicts.

Overview

Property	Value
Format id	mif
Class	MapInfoIterable
Extensions	.mif (companion .mid handled by the driver)
Read	Yes
Write	No
Extra	geospatial (fiona)
Maturity	experimental

Record shape

{
    "type": "Feature",
    "id": "...",
    "properties": {...},
    "geometry": {"type": "Polygon", "coordinates": [...]},
}

Requires a filename (not a stream). Uses Fiona's MapInfo File driver with streaming feature iteration.

Usage

from iterable import open_iterable

with open_iterable("parcels.mif", format="mif") as source:
    for feature in source:
        print(feature["id"], feature["geometry"]["type"], feature["properties"])

Install with pip install iterabledata[geospatial].

Parameters

No format-specific iterableargs. A filesystem path is required (streams and codecs are not supported). Companion .mid attribute files are resolved by Fiona's MapInfo driver when co-located.

Error Handling

• Missing dependency: optional libraries raise ImportError with an install hint (pip install 'iterabledata[<extra>]' when an extra exists).
• Read-only: opening with mode="w" raises WriteNotSupportedError or ValueError.
• Bad or unsupported input: may raise ValueError, OSError, or library-specific errors.
• See Troubleshooting for decoding, detection, and engine issues.
